    摘要: In a winder mandrel (1) with radially movable spreading segments (2) which are arranged on the periphery, a mandrel body (3) and a pulling rod (4), the spreading segments (2) and/or the mandrel body (3) and/or the pulling rod (4) are configured as magnets.A method for operating a winder mandrel of this type provides for the spreading segments (2) and/or the mandrel body (3) and/or the pulling rod (4) to be configured as electromagnets, and for the supply voltage of the electromagnets to be switched on during initial winding of the beginning of the strip, lowered during the rolling and raised again when the strip is slipped out.
